<p>A connector (1) for connecting together elongated frame bars (10) having T-shaped grooves (13) on side surfaces is a single elongated structure having a longitudinally uniform cross-sectional shape. The connector (1) has a central wall (3) and is symmetric with respect to the plane of this central wall (3). Pairs of wings (5,7) protrude from the central wall (3) to be inserted into the grooves (13) in the frame bars (10) to be connected. The wings (7) of one of the pairs protrude perpendicularly to the central wall (3). The wings (5) of the other pair are cross-sectionally Z-shaped so as to be able to elastically engage in and with the grooves (13) of the frame bars (10). Each wing (5,7) has a mutually outwardly protruding part (5c,7c) with a slope for being pressed against edges (17) of the grooves (13) such that the connector (1) can be correctly positioned. <IMAGE></p> |
